gamete

 [gam´ēt]
1. one of two haploid reproductive cells, male (spermatozoon) and female (oocyte), whose union is necessary in sexual reproduction to initiate the development of a new individual.
2. the malarial parasite in its sexual form in a mosquito's stomach, either male (microgamete) or female (macrogamete); the latter is fertilized by the former to develop into an ookinete. adj., adj gamet´ic.

gam·ete

(gam'ēt),
1. One of two haploid cells that can undergo karyogamy.
2. Any germ cell, whether oocyte or sperm.
[G. gametēs, husband; gametē, wife]

gamete

(găm′ēt′, gə-mēt′)
n.
A reproductive cell having the haploid number of chromosomes, especially a mature sperm or egg capable of fusing with a gamete of the opposite sex to produce a zygote.

ga·met′ic (-mĕt′ĭk) adj.
ga·met′i·cal·ly adv.

gamete

Genetics A mature ♀ or ♂ reproductive cell–sperm or ovum/egg with a haploid set of chromosomes–23 for humans. See Chromosome, Haploid, Macrogamete, Microgamete, Nullisomic gamete.

(gam'ēt)
1. One of two haploid cells undergoing karyogamy.
2. Any germ cell, whether oocyte or sperm.
[G. gametēs, husband; gametē, wife]

gamete

A cell, such as a sperm or ovum, possessing half the normal number of chromosomes (haploid) and capable of fusing with another gamete in the process of fertilization, so that the full (diploid) number of chromosomes is made up. From the Greek gamos , marriage.

gamete

or

germ cell

a specialized HAPLOID cell that fuses with a gamete from the opposite sex (or mating type) to form a diploid ZYGOTE. In simple organisms, the process is called isogamy (see ISOGAMETE), and OOGAMY in more complex organisms. In animals where oogamy occurs male gametes are called sperm, the female gametes eggs. The situation in higher plants is more complicated, but essentially the male gamete is the generative nucleus found in the POLLEN GRAIN while the female gamete is the egg cell found within the EMBRYO SAC.

Gamete

An egg (ovum) from the female or a mature sperm from the male.
